ABSTRACT

A study was conducted during July 2020 to June 2021 regarding yield and mineral status of bottle gourd under salinity condition in the south-central coastal region of Bangladesh. The study locations were PSTU farm, Dumki; south Muradia, Dumki; Nauvanga, Kalapara; Pakhimara, Kalapara of Patuakhali district and Sawdagarpara, Taltoli of Barguna district having EC level 0.87, 0.97, 4.4, 4.8 and 6.4 dSm-1, respectively. The yield of bottle gourd was increased with the increasing of soil EC level. Bottle gourd was analyzed for determining of minerals such as P, K, Ca, Mg, S, Na, Zn, Fe, Cu and Mn. The findings of the study revealed that P, Ca, S, Zn, Fe, Cu and Mn was in decreasing trend with soil EC level whereas, K, Mg as well as Na was in increasing trend with soil EC level. Results indicated that, the bottle gourd was moderately salt tolerant (soil EC value up to 6.4 dSm-1) and it can be recommended to grow commercially in the study areas.

Key words: Bottle gourd, yield, minerals, salinity, coastal area.
